Description

Technical field

The technical solution relates to a rigid or semi-rigid container having a polygon in cross section, made by folding a paper blank, which can be closed and opened by a combination of several actions.

State of the art

The process of assembling boxes creates many problems that must be taken into account when constructing them: considerable time is spent on assembly, qualified personnel are required, and actions necessary for deformation of parts of the walls of the box, on which its strength and shape preservation, depend on assembly.

To solve the problem with the time spent on assembly, solutions have been developed related to the so-called "fast bottom" structures, that is, to the structures of the bottom parts of the boxes, which can be quickly assembled while fastening the bottom valves without the use of improvised means and fasteners (US patent 6152359, B65D 5/00, publ. 28.11.2000, patent US 5893458, B65D 5/10, publ. 04/13/1999).

A feature of the “fast bottom” designs is that when assembled, they are bent from the side walls of the valve and are interconnected by a lock connection, which allows you to quickly assemble the bottom of the box. However, such a lock connection is unreliable.

Known packaging, which is a box made of corrugated cardboard by the method of bending parts of a sheet blank, which includes side walls sequentially connected through the bending lines, bending each relatively adjacent wall to form an open box and having flaps from one edge of the valve, bending towards each other to form the bottom of this box, while the valves associated with one two oppositely located side walls, each made with a cutout and a protrusion for placed the protrusion of one of these valves in the cutout of another valve (RU 2323863, B65D 5/36, B65D 5/42, publ. 05/10/2008).

This decision was made as a prototype.

In this box, to obtain the bottom, the end wall valves are first bent, and then the valves are bent from the side walls adjacent to each other. In this case, the protrusion of one valve is brought into the cutout of another valve, and from the tongue it is brought out and placed as supports on the valve of the end walls. It turns out the bottom, but it does not carry a load, since when the pressure on the bottom of the cavity of the box, the protrusion comes out of the cavity and the bottom opens. There is no mechanism for fastening valves to prevent their opening. Boxes with such a bottom design are used for light weight goods or for goods whose box must be supported from the bottom. Such boxes are used only as packaging to preserve the presentation of the packaged product.

When using boxes formed from a single sheet in the confectionery industry, first a bottom is created in them, which closes the cavity for placing goods in it, for which the box is used for storage, transportation and sale. The bottom of the box at the stage of its filling with the goods is carrier and must support the weight of the loaded goods.

The formation of the bottom, as well as the lid of the box, should not be a long process and should not require complex skills. After the goods are loaded into the box and the box lid is closed, the bottom and lid structures should not allow their unauthorized opening, i.e. they must be made with the ability to perform the function of the locking mechanism. Moreover, such a “lock” should be easy to assemble and operate when it is closed, at the same time, its design should not allow it to open when it is accidentally moved.

The technical result of the claimed utility model is to simplify the design of the end parts of the box, ensuring the indissolubility of the assembled box when the product is in it, and reducing the time spent on packaging the goods.

The specified technical result is achieved by the fact that the box in the form of a polyhedron with lock joints is made on the basis of a flat die cut, consisting of one rectangular sheet, divided vertically by scoring into equal parts, the number of which corresponds to the number of faces in the box, horizontally a rectangular sheet is divided by scoring into three parts, of which the central part is designed to form the side surface of the box, and the upper and lower parts - to form the castle joints, with which s forms a closed volume of the box. In this case, the upper and lower parts of the die cutting are the same size and are a mirror image of each other relative to the horizontal axis of symmetry. The upper and lower edges of the die cutting can have round-shaped cutouts, convex side facing the horizontal axis of symmetry. On the upper and lower parts of the die cut, two horizontal creases and parallel inclined creases are made, the number of which is equal to the number of faces in the box, and γ is the angle of inclination of the inclined crease to the crease, separating the corresponding (upper or lower) part of the die from the central one, is 360 ° / n, where n is the number of faces in the box. A cut in the form of a quadrangular figure is made between two adjacent inclined creases in the die-cutting, formed by two parallel straight lines and two curves, each of which is formed by the conjugate segments of a circle and an ellipse, the segments of the circle with the convex side facing the notch and the segments of the ellipse facing the notch, the conjugation point the segment of the circle and the ellipse is located above the intersection of the curve of the quadrangular figure of the first horizontal scoring, located above the scoring, separating the central part be die-cut from the upper (lower) side. Each of the parallel straight sides of the cutout in the form of a quadrangular figure coincides with a segment of one of the adjacent inclined creases.

One of the sides of the central part of the die cutting is made integral with the glue valve, trapezoidal, designed to form a connection with the opposite edge of the central part, the long base of which is equal to the height of the central part. On the opposite lower and upper edges of the die cutting, one trapezoidal glue valve is made, the long base of each of which is equal to the distance from the upper (lower) edge of the die cutting to the second horizontal scoring.

These features are significant and interconnected with the formation of a stable set of essential features sufficient to obtain the desired technical result.

This useful model is illustrated by a specific example of execution, which, however, is not the only possible one, but clearly demonstrates the possibility of achieving the desired technical result.

In the General case, the package is a box made of cardboard by the method of bending parts of the die 1, which includes the faces 7 of the box body connected in series through the bending lines, each bending relatively relatively adjacent faces to form an open box. The last of the faces of the central part of the box body is equipped with a trapezoidal glue valve 8, which can be made at the same time as a continuation of any of the extreme edges of the central part of the box body.

The trapezoidal glue valve 9 can be made at the same time as a continuation of any of the extreme edges of the upper part of the box body. In the lower part of the box body, it is also made as a continuation of any of the extreme edges of the lower part of the box body (in Fig. 1 the glue valve in the lower part of the body is shown, without indicating its position) a trapezoidal glue valve.

Glue valves are designed to connect the central, upper and lower parts of the box into a polyhedron with open end faces.

The upper part of the polyhedron, on which horizontal scoring 2 and 4, shaped quadrangular openings 3 are made, and which is separated from the central part by a horizontal scoring 11 when connecting its side faces with an adhesive valve, forms a lock joint by applying force along the symmetry axis of the lock joint with subsequent application of torque around the axis of symmetry of the castle connection. The moment of application of torque is determined by the beginning of the addition of the petals of the castle connection located below the creasing 4. When applying to the castle connection of the torque, the elements of the castle connection are folded along the lines of the inclined creasing 12.

When closed, the lock connection looks like that shown in FIG. 2, 3, 4 and 5.

The quadrangular cutout 3 is made in such a way that, when a force is applied to the castle joint along the symmetry axis of the castle joint, its elements located below the scoring 4 do not cling to each other, but fold, forming a continuous surface, as shown in FIG. 2-4.

The relationship of the angle of inclination γ of the inclined scoring 12 to the scoring 11, which separates the top of the box from the central, with the number of faces provides at the time of application of the torque to the castle connection the addition of elements of the castle connection without engaging each other.

The castle connection in the lower part of the die-cutting box coincides in all elements with the castle connection in its upper part, with the difference that all the elements of the castle connection in the lower die-cutting are made mirror-like with the corresponding elements of the castle connection of the upper die-cutting of the box.

This embodiment of the locking joints in the lower and upper parts of the box to achieve the declared technical result.
